class Str_Buffer{ public static void main(String args[]){ StringBuffer sb = new StringBuffer("Hello"); System.out.println("buffer before= " + sb); System.out.println("charAt(1) before= " + sb.charAt(1)); sb.setCharAt(1, 'i'); sb.setLength(2); System.out.println("buffer after= " + sb); System.out.println("charAt(1) after= " + sb.charAt(1)); } }

Q44: Java Program to use all the methods defined by string class (substring, indexOf, length, charAt, getchars etc).
class StringMethods{ public static void main(String args[]){ String s = "This is a demo of the getchars method."; int start = 10; int end = 14; char buf[] = new char[end - start]; s.getChars(start, end, buf, 0); System.out.println(buf); String org = "This is a test. This is, too."; String search = "is"; String sub = "was"; String result = ""; int i; do{ System.out.println(" "); System.out.println(org); i = org.indexOf(search); if(i != -1){ result = org.substring(0, i); result = result + sub; result = result + org.substring(i + search.length()); org = result; } }while(i != -1); } }
